Meta AnalysisAppropriate Duration of Perioperative Intravenous Administration of Lidocaine to Provide Satisfactory Analgesia for Adult Patients Undergoing Colorectal Surgery: A Meta-Analysis of Randomized Controlled Trials.
Perioperative lidocaine infusion has been reported to alleviate pain intensity after colorectal surgery. However, there is no consensus on whether prolonged lidocaine infusion is more effective than short lidocaine infusion. This meta-analysis aimed to determine an appropriate duration of lidocaine infusion in patients undergoing colorectal surgery. ⋯ The analgesic effect of intravenous lidocaine may depend on the duration of infusion, and our results suggest that lidocaine infusion should be administered for at least 24 hours after colorectal surgery. Since overall evidence quality was low, further high-quality, large-sample trials are needed to explore an optimal lidocaine infusion strategy in patients undergoing colorectal surgery.

Randomized Controlled TrialSugammadex Versus Neostigmine for Recovery of Respiratory Muscle Strength Measured by Ultrasonography in the Postextubation Period: A Randomized Controlled Trial.
Although sugammadex is well known for its use in reducing the incidence of residual neuromuscular blockade, this has not always been translated to improved clinical measures of postoperative respiratory muscle strength. Expiratory muscles play an important role in airway clearance and inspiratory muscle capacity augmentation, yet they have not been well studied. Therefore, we tested the hypothesis on whether sugammadex could enhance expiratory muscle strength recovery more completely than neostigmine in the immediate postextubation period. ⋯ Sugammadex provides a more complete recovery of expiratory muscle strength than neostigmine at TOFR ≥0.9. Our data suggest that the respiratory muscle strength might still be impaired despite TOFR reaching 1.

Meta AnalysisHigh-Flow Nasal Cannula for Apneic Oxygenation in Obese Patients for Elective Surgery: A Systematic Review and Meta-Analysis.
Obese patients desaturate rapidly during the apneic period after induction of anesthesia for elective surgery. Administration of oxygen using high-flow nasal cannulae (HFNCs) may prevent desaturation in nonobese patients compared to facemask (FM) preoxygenation. The aim of this meta-analysis was to compare the effectiveness of HFNC to FM preoxygenation techniques in reducing preintubation desaturation in obese patients undergoing elective surgery. ⋯ There may be no difference between HFNC and FM preoxygenation in preventing oxygen desaturation <92% or the lowest oxygen saturation before intubation. Preparation remains important to prevent and manage desaturation during induction of obese patients.
